Delicious Low-Fat Mini Banana Bread Squares: Your Perfect Portion-Controlled Treat
Indulge in the delightful taste of banana bread without the guilt! Our Low-Fat Mini Banana Bread Squares offer a smart and delicious solution for enjoying your favorite comfort food in perfectly portioned servings. Baked in a convenient mini bar cookie pan, these individually sized treats are not only incredibly moist and flavorful but also designed with your health and portion control in mind. This recipe leverages the natural sweetness and moisture of ripe bananas, minimizing the need for excessive fats while delivering a truly satisfying experience.
The beauty of these mini banana bread squares lies in their simplicity and versatility. They are ideal for breakfast on the go, a wholesome afternoon snack, or a light dessert. By utilizing a specific mini bar pan with square-shaped cavities, we ensure each piece is uniformly baked and easy to manage, making them an excellent choice for meal prep or gatherings where individual servings are preferred.
One of the primary advantages of baking in a mini bar pan is the inherent portion control it provides. Each square is a complete serving, eliminating the temptation to overindulge. While this specialized pan is highly recommended for achieving those perfect little squares, don’t worry if you don’t own one. This versatile recipe can easily be adapted. You can substitute a pan with multiple mini loaf cavities for small, rectangular loaves, or even a standard muffin tin for round banana bread muffins. Even a regular loaf pan works, though you’ll need to adjust baking time and slice the bread into smaller portions after cooling. The key is to achieve that delightful banana bread taste, regardless of its final shape.
Our recipe for low-fat banana bread stands out because it contains very little added fat, yet sacrifices none of the expected moistness. This is achieved through a careful balance: a small amount of oil works in conjunction with the significant contribution of 1 ½ large, very ripe bananas. These overripe bananas are crucial, as they provide natural sweetness and a creamy texture, ensuring your banana bread squares remain incredibly tender and flavorful without relying on heavy amounts of butter or oil. It’s a testament to how simple ingredient swaps can lead to healthier, equally delicious results, making this an ideal recipe for those seeking wholesome yet indulgent treats.
Baking low-fat treats doesn’t mean compromising on taste or texture. In fact, ripe bananas are your best friend in such recipes. As bananas ripen, their starches convert to sugars, intensifying their sweetness and making them incredibly soft and easy to mash. This natural sweetness reduces the need for excessive added sugar, contributing to the overall healthier profile of these squares. Furthermore, their high moisture content acts as a fat substitute, keeping the bread incredibly moist and tender. When choosing your bananas, look for ones with plenty of brown spots or even entirely brown skins – these are perfectly ripe for banana bread and will yield the best results.
Beyond the primary ingredients, the leavening agents – baking powder and baking soda – play a vital role in creating the light and airy texture characteristic of great banana bread. Baking soda reacts with the acidic components in the batter (like buttermilk and the bananas themselves) to produce carbon dioxide, which helps the bread rise. Baking powder provides an extra lift, ensuring a beautiful, fluffy crumb. The touch of salt enhances all the flavors, balancing the sweetness and making the banana taste even more pronounced. This careful combination of ingredients ensures each mini square is a delightful bite, perfectly risen and bursting with flavor.

Low Fat Banana Bread Squares
Cookie Madness
Pin Recipe
Ingredients
- 1 ½ large bananas whole (very ripe, with brown spots for best flavor and moisture)
- ⅓ cup granulated sugar or sweetener equivalent (70 grams, adjust to your preference for sweetness)
- 1 large egg (helps bind the ingredients and contributes to texture)
- 1 ½ teaspoons vanilla extract (for a comforting aroma and flavor)
- 2 teaspoons grapeseed oil or canola oil (light oils for minimal fat but maximum moisture)
- 1 teaspoon baking powder (ensures a light and airy texture)
- ¼ teaspoon baking soda (reacts with acids for lift and tenderness)
- ¼ teaspoon salt (enhances all the flavors)
- ⅞ cup all-purpose flour (110 grams, ensures proper structure)
- 3 tablespoons buttermilk or milk mixed with ½ tsp. lemon juice (adds moisture and activates baking soda; regular milk with lemon juice is an easy substitute)
Instructions
-
Prepare Oven and Pan: Preheat your oven to 325 degrees F (160 degrees C). This lower temperature helps ensure an even bake for smaller items. Generously spray a 12-indentation mini bar pan with a flour-added baking spray. This type of spray is excellent for preventing sticking and ensuring easy release, especially with intricate mini molds. If you don’t have this specific spray, you can grease and flour the pan thoroughly.
-
Mash Bananas and Combine Wet Ingredients: In a large mixing bowl, begin by mashing your very ripe bananas. You can use a hand-held electric mixer for a super smooth consistency, or a fork or spoon for a slightly chunkier texture, depending on your preference. Once mashed, beat in the granulated sugar and the large egg. Continue to beat the mixture until it appears smooth and well combined, ensuring the sugar is dissolved and the egg is fully incorporated, which contributes to a fine crumb.
-
Add Liquids and Leavening Agents: Next, beat in the vanilla extract and your chosen oil (grapeseed or canola). These add flavor and a touch of moisture. Follow this by beating in the baking powder, baking soda, and salt. Make sure these dry leavening agents are evenly distributed throughout the wet mixture, as this is crucial for the proper rise and texture of your banana bread squares.
-
Gently Fold in Dry Ingredients: Switch to mixing by hand to avoid overmixing. Gradually stir in the all-purpose flour until just combined. Overmixing flour can lead to tough banana bread, so stop as soon as no dry streaks remain. Then, gently stir in the buttermilk (or your milk-lemon juice mixture). This final liquid addition helps achieve the perfect batter consistency and activates the baking soda for optimal leavening.
-
Fill Pans and Bake: Carefully divide the banana bread batter equally among all 12 indentations of your prepared mini bar pan. Even distribution ensures that all squares bake uniformly. Place the pan on the center rack of your preheated oven and bake for approximately 25 minutes. The baking time may vary slightly depending on your oven, so watch for a golden-brown color and test for doneness by inserting a toothpick into the center of a square – it should come out clean.
-
Cool and Serve: Once baked, remove the pan from the oven and let the banana bread squares cool in the pan for about 10 minutes. This crucial cooling period allows the squares to firm up, making them much easier to remove without breaking. After 10 minutes, carefully transfer them from the pan to a wire rack to cool completely. Enjoy these perfectly portioned, low-fat treats warm or at room temperature!
